IRCT20260903070901N1 IRCT 2026-09-07 Islamic Azad University The effectiveness of positive psychotherapy The effectiveness of positive psychotherapy on marital satisfaction, cognitive emotion regulation, and marital burnout in women affected by marital infidelity. 2026-10-01 anticipated 30 Complete https://irct.ir/trial/93081 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Education/Guidance, Randomization description: In this study, a simple randomization method is used to assign participants to two experimental groups (positive psychotherapy) and control. The randomization unit in this study is women affected by marital infidelity who are referred and eligible for the study. First, a complete list of volunteers who are selected based on the study's inclusion criteria (including the age range of 20 to 50 years, minimum diploma education, at least 3 years of cohabitation history, and more than 6 months have passed since the disclosure of the spouse's infidelity) and the absence of exclusion criteria (such as physical illnesses that interfere with the treatment process and the use of psychiatric medications) is prepared. Then, a unique numerical identification code is assigned to each participant. These codes are entered into the Random Number Generator software and a random number is generated for each individual. After generating these numbers, the participants are sorted in ascending order based on the value of the random number. Then, the individuals are assigned to two groups; The first 15 people on the list are assigned sequentially to the experimental group (recipients of the positive psychotherapy intervention) and the next 15 people to the control group (on the waiting list). With this method, the order of entry into the study and the researcher's knowledge of the participants will not play any role in determining the group. To conceal the allocation, the person responsible for entering the data and carrying out the randomization process in the software will be independent of the intervention administrators and the evaluators of the research variables (including marital satisfaction, cognitive emotion regulation, and marital burnout) and will not have the possibility of knowing the process of implementing the sessions or changing the allocation of the individuals. Also, the identification codes of the participants are kept confidential and separate from their other personal information. Therefore, it will not be possible to predict the assigned group for each participant before the randomization process, Blinding description: In order to control bias and improve the internal validity of the research, this study was designed with a double-blind protocol; in this way, the outcome assessor and data analyst will be kept unaware of the allocation of women affected by marital infidelity to the experimental (positive psychotherapy) and control groups. In this process, the outcome assessor will collect and measure the dependent variables (marital satisfaction, cognitive emotion regulation, and marital burnout) at all stages of the pretest, posttest, and follow-up, without knowing the assigned group of the participants, in order to prevent bias in the measurement; also, all raw data will be provided to the statistical analyst with anonymous codes (such as groups 1 and 2), and the true nature of the groups (positive intervention group versus control group) will not be revealed until the end of the data analysis process. All allocation steps are performed by an individual independent of the research team, and allocation codes are decoded only after the final completion of statistical analyses. N/A Damage from marital infidelity. Intervention 1: Intervention group: Positive Psychotherapy (PPT) sessions will be based on the treatment protocol designed by Mirdrikvand et al. (2019). The sessions of this intervention will be conducted in 13 90-minute sessions (one session per week) in a group setting for the experimental group. Positive psychotherapy is an approach that aims to identify and strengthen the secretary's capabilities, cultivate positive emotions, and reconstruct the meaning of lived experiences, helping women affected by marital infidelity to improve their sense of self-worth, resilience, and psychological well-being by utilizing internal resources, instead of focusing solely on the damage and ruminations caused by the breach of contract. This approach has main educational and therapeutic axes that lead to improving cognitive emotion regulation, increasing marital satisfaction, and reducing marital burnout; these axes include: establishing familiarity, explaining the therapeutic logic, and examining the role of the lack of positive resources and emotions in the continuation of individual and interpersonal problems; Assessing and measuring the clients' secretarial capabilities through a questionnaire and discussing how to use strengths; cultivating special capabilities and shaping objective and achievable behaviors; reviewing good memories versus bad memories and discharging bitter emotions along with recognizing their effects on mental health; teaching and applying forgiveness techniques as a powerful tool for transforming negative emotions into neutral or positive emotions; explaining and reinforcing the concept of gratitude and highlighting positive memories of life; teaching the skill of contentment versus maximization to strengthen commitment and realism in relationships; strengthening the components of hope and optimism in the face of interpersonal failures and rejections and providing coping strategies; redefining love, secure attachment, and active-constructive response styles; drawing and examining the family tree of family capabilities; teaching the sense of taste and tasting pleasures to intentionally become aware of pleasant experiences and protect them from harm; Utilizing the gift of time in service to others and promoting a sense of meaning; and finally integrating the components of pleasure, commitment, and meaning in the form of a "full life" model, summarizing achievements, and consolidating the durability of the intervention's effects. The main emphasis of this treatment is to replace positive emotional experiences, strengthen psychological resilience, rebuild positive emotions, and develop personality capabilities in the face of trauma and the crisis of marital infidelity. Intervention 2: Control group: They do not receive any intervention or treatment. No - There is not a plan to make this available Justification or reason for not sharing IPD is Participant data is completely confidential and I do not intend to publish it.
